2 Safety precautions
Please note the following warnings regarding the hazards associated with development systems.
Table 1 Safety precautions
Warning: The DC link potential of this board is up to 1000 VDC. When measuring
voltage waveforms by oscilloscope, high voltage differential probes must be used.
Failure to do so may result in personal injury or death.
Warning: The evaluation or reference board contains DC bus capacitors which take
time to discharge after removal of the main supply. Before working on the drive
system, wait five minutes for capacitors to discharge to safe voltage levels. Failure to
do so may result in personal injury or death. Darkened display LEDs are not an
indication that capacitors have discharged to safe voltage levels.
Warning: The evaluation or reference board is connected to the grid input during
testing. Hence, high-voltage differential probes must be used when measuring voltage
waveforms by oscilloscope. Failure to do so may result in personal injury or death.
Darkened display LEDs are not an indication that capacitors have discharged to safe
voltage levels.
Warning: Remove or disconnect power from the drive before you disconnect or
reconnect wires, or perform maintenance work. Wait five minutes after removing
power to discharge the bus capacitors. Do not attempt to service the drive until the bus
capacitors have discharged to zero. Failure to do so may result in personal injury or
death.
Caution: The heat sink and device surfaces of the evaluation or reference board may
become hot during testing. Hence, necessary precautions are required while handling
the board. Failure to comply may cause injury.
Caution: Only personnel familiar with the drive, power electronics and associated
machinery should plan, install, commission and subsequently service the system.
Failure to comply may result in personal injury and/or equipment damage.
Caution: The evaluation or reference board contains parts and assemblies sensitive to

installing, testing, servicing or repairing the assembly. Component damage may result
if ESD control procedures are not followed. If you are not familiar with electrostatic
control procedures, refer to the applicable ESD protection handbooks and guidelines.
Caution: A drive that is incorrectly applied or installed can lead to component damage
or reduction in product lifetime. Wiring or application errors such as undersizing the
motor, supplying an incorrect or inadequate AC supply, or excessive ambient
temperatures may result in system malfunction.
Caution: The evaluation or reference board is shipped with packing materials that
need to be removed prior to installation. Failure to remove all packing materials that
are unnecessary for system installation may result in overheating or abnormal

3 Introduction
The EVAL-M1-301F evaluation board is a part of the iMOTION™ modular application design kit for drives
(iMOTION™ MADK). In order to run a motor, the mating power board is required to interface this evaluation
board.
The MADK platform is intended for use with various power stages with different control boards. These boards
can easily be interfaced through the 20-pin iMOTION™ MADK M1, or the 30-pin iMOTION™ MADK M3 interface
connector. This board is equipped with a 20-pin M1 connector and is intended for running a single motor.
This evaluation board is designed to give comprehensible solutions of sensorless control of permanent magnet
motors over the full speed range. It provides Hall-sensor based or sensorless controls applying 3-phase and
type 3 of 2-phase modulation. PC interface is via a micro-USB connector and the on-board debugger is
galvanically isolated. The PC interface provides a UART connection to the MCE as well as a serial wire debug
(SWD) channel to the MCU.

documentation for more details.
Note: The on-board debugger section of EVAL-M1-301F is galvanically isolated from the controller
section and the attached power board. In order to program the parameters or firmware to the
IMC301A-F064 controller, the 3.3 V DC voltage needs to be supplied to the controller portion of the
EVAL-M1-301F. This voltage can either be supplied by the power board (MADK power boards are
designed to supply the 3.3 V to the control board through M1 or M3 connector) or by feeding the 3.3
V DC voltage to the control board through some of the available 3.3 V access/test points, if the
power board is not attached to the EVAL-M1-301F control board.
All the latest firmware files for different types of iMOTIONTM control ICs are available for download via Infineon

website (http://www.infineon.com/imotion-software).
5.3 Working with the MCU
The microcontroller in the IMC301A-F064 is based on an Arm® Cortex® M0 core allowing the use of a wide range
of development tools and available software solutions.
Connection to the MCU is offered via the standard serial wire debug (SWD). The SWD interface is routed via the
galvanic isolation to the on-board interface. The debug interface is based on Segger® J-Link technology. The
respective DLL is installed on the PC during installation of the above-mentioned iMOTION tools, namely the
MCEDesigner. Alternatively, the installation of the respective driver can be updated from the Segger website.
Configuring, setting up and programming the embedded MCU is beyond the scope of this user guide. Please
refer to the Hardware Reference Manual of the IMC300 series and the CMSIS pack.
